Ohio state Sen. Matt Dolan - the moderate Republican who lost to Trump-backed J.D. Vance in a primary - is now setting his sights on Democrat Sherrod Brown's U.S. Senate seat in 2024. 'I am unapologetically committed to putting the needs of Ohio first and delivering results as our next U.S. Senator,' Dolan said in a statement. 'With the courage of my convictions, clarity of purpose and a resolute focus on the challenges and opportunities facing our beloved state, I am ready to lead.'
